A patient requires 2 g of amoxicillin. The available medication is 250 mg capsules. How many capsules should the nurse administer per dose?
4 capsules
6 capsules
10 capsules
8 capsules
The Correct Answer is D
Calculation:
- Identify the ordered dose and capsule strength
Ordered Dose: 2 g (2000 mg)
Capsule Strength: 250 mg per capsule
- Calculate the number of capsules to administer
Number of Capsules = Ordered Dose ÷ Capsule Strength
Number of Capsules = 2000 ÷ 250
= 8

Correct Answer is C
Explanation
Calculation:
- Identify the child’s weight and recommended dose range
Weight: 27 kg
Recommended dose: 25–50 mg/kg/day
- Calculate the safe dosage range
Minimum dose = 25 × 27
= 675 mg/day
Maximum dose = 50 × 27
= 1350 mg/day
Safe range = 675–1350 mg/day
- Compare the ordered dose to the safe range
Ordered Dose: 150 mg/day
150 mg is below the minimum recommended dose of 675 mg/day. The ordered dose is subtherapeutic and may not provide adequate treatment.
Correct Answer is A
Explanation
A. Insensible: Insensible fluid loss occurs through evaporation from the skin and respiratory tract and is not easily observed or measured. It contributes to daily water loss and is influenced by factors such as temperature, humidity, and respiratory rate.
B. Voluntary: Voluntary fluid loss refers to fluid excretion that can be consciously controlled, such as urination. It does not describe natural, unperceived losses through skin or respiration.
C. Regulated: Regulated fluid loss typically involves processes under physiological control, such as renal excretion, which is monitored by homeostatic mechanisms. Insensible loss is largely passive and not actively regulated.
D. Measured: Measured fluid loss includes outputs that can be quantified, such as urine, vomit, or drainage. Insensible losses cannot be directly measured.
